Application filed June 19, 1925. Serial No. 38,351.-,

To all whom it 17mg concern: a

Be it known that I, HARRY D. CLINTON, a citizen of the United States,residing at Johnson City, in the county of Broome'and State of New York;have invented certain new and useful Improvements in Jack Spools; and Ido herebydeclare the following to be a full, clear, and exactdescription of the invention, such 'aswill enable others skilled in theart towhieh1it appertains to make and use the same. 1

This invention relates to jack spools such as are used especially by:the =woolen and Tworsted manufacturers and; in the. knitting trade, inthe manufacture of yarn, and also to ship yarn from one branchto anotherorfrom one mill to another; such spools being made of differentlengths-varying from 24 to 7 2 inches between the heads, andthe headsvarying'in diameter from 6to l2 inches. The spoolsare provided withgud'geon pins which project from opposite ends-thereof. VOrdinarily thegudgeon is secured tothe 1' endof a 'wooden barrel by'simply' boringvaholein the end of'tlie barrel and"a trans- 'verse-hole or slot'toreceive a "nut which is screwed on a threaded part of the gudg'eon whichis inserted in thefirst mentioned :hole. Such acconstruction isdefective inasmuch as Ythe gudgeon, is constantly-becoming loose mm is adiflicult matter to screwythea'nut on securely "on the inside ofthe'barrel and when the gudgeon becomesloose it causes a'great deal-oftrouble, asthe head is apt off over the end of the spool,usual1ycausingconsiderable loss, and it'is desirable. that the headshould bedetachable, becau'sefre- -'quent1'y the-heador barrel breaks, :in whichicase a new head can be used with the old barrel on a new barrel with anoldhead,

but even-though the head is detachableit should also be possible toapply'theheadfso that it cannot wo'rkloose or come oftothe'rwise than byactual intent. 5

The objects" of my invention are. to overcome the dilficultieshereinbefore' mentioned -incident to the use ofjack spools asheretoloose or detached in actualuse but may .'be 1 easily separatedwhen it is desired to" remove the head in case of breakageior' for'other cause. 1

Fig. 2 is an end viewof the same, x

broken away end portion of the "The invention= will first be hereinaftermore particularly desc'ribed,with reference to the accompanyingdrawings, which are to be taken as a part'of this specification,

and then pointed out in the claims'at the end ofthe description 1 In-sad drawings, Fig. 1 is aplan View of a jack spool constructed inaccordance with my invention;

Fig; 3 is a vertical 'sectionallviewr of a I spool shown in Figs. '1 and2; and;

.- =-'F1g. 4 isa perspectiveview of'ithe several parts shown In Flgs. 1to 3 mposition for assembling 'and securing said parts together.

Referring to said drawings in'which the same reference letters are usedto denote corresponding parts in different views,-'-the letter A denotesa 'wooden barreljwhich may be of tubularform or provided with a socketin each end 'thereof,"xto receive a 'bushing'B, preferably of wood,inserted in jbdlt Cficarrying the f gudg'eonfpin and an oblong recess bextending transversely of said opening to receive an: oblong-- head '0on the inner end of said bolt, to prevent the bolt "from turning. Thebolt has a threaded 'portion' intermediate its ends on which is to'comeoff andI permit the yarn toslOughscrewed a nut D, whereby the/head ofthe square, is then screwed on the threaded porerably of'hard fibre,having a square for polygonal opening'therein, is placed ontthe boltwith said second nut fitting snugly within the opening through the head,so

that/said second nut and the head will roof the spool barrel Thereupon ajam nut or metal washel G having a peripheral por 'tion of the bolt Cand a spool head*F,'pref as to firmly press the head againstthe end 5tion 9 bearing upon the outer side of the head and a central boss 1 orprotuberance g bearing upon said second-nut, is screwed on the threadedpart of the bolt for securing the several parts together, said head. andwasher being provided with oppositely disposed itwoijam nuts.Theassembled parts are thus firmly secured together and held in place soas to prevent the head or the gudgeon from turning or becoming loose orthe head from coming oft, zuntil sufiicient force is :applied'itounscrewthewasher by the application of a spanner wrench for -that purpose, landvthe 'fibre head will be firmly held between the end of the spool barreland the nut :E with nd-tendency to become loose until the washer isunscrewed, whereupon -.the=head may. be easily taken-ofi of the-barrelby means .of a. spanner wrench applied thereto.

Preferably a steel ferrule orsleeve H is 1 secured on a reducedendportion of the barrel so as toabut against the fibre' head andPIEVGIItvWBZLIfiD the ends of the barreland also. strengthen the entireconstruction.

Suchv ferrule however may be dispensed with, especiallyiif the barrel-isanade 0f :har'der J material :than wood.

Havingthusdescribedsmy invention, what .I claim as new anddesire tosecure by LetterslPatentof the United. States'is:

1. The combination, in .a device of the character described, of a barrel:having a bushing inserted in one end thereof, said ebushing having alongitudinal opening therethrough. and. 2 a recess .at the inner. endthereof extending across said iopening, a ibQlt inserted insaid openinghaving an intermediatethreaded portion vand an oblong head on .its innerend fitting in said recess, 1 the free end of said bolt projecting:beyond theaouterf end of said bushing,a nut screwed "on said. bolt soas to draw said headinto said recess, a second .nut screwed on said boltadjacent the first named =nut, a disklikeade-vice screwed .on said boltadjacent said "second nut, anda spool-head interposed between saidsecond aunt and said device, said :read having acentral polygonal.opening thereinfitting .over said seconds-nutso as to cause the nut andhead to rotate together; said device having a centrally disposed ipartadapted to contact with said second nut :and a peripheral portionadapted tocontact with :t-he'outer side of said head for clainping helatter tightly against the end of said-barrel.

2. "A device of the character :described comprising a tubular barrelhaving a bushing inserted-in each endthereof, said bushing having alongitudinal opening there- 'through and a recessextending across saidopening at the inner end thereof, a bolt inserted in .said openinghaving an oblong head on its inner end fitting in said recess and anintermediate threaded portion and a gudgeon pin on its free endprojecting beyond the end of the barrel, a jam nut screwed on said boltadapted to drawsaid head'into said recess, a second nut of polygonalforrn screwed on said bolt adjacent the filSlZ'IlHITlBCl nut,-aspool-head having a central polygonal opening therein; fitting :oversaid-second nut,.:and a washer-like device or jam nut-screwed on saidbolt and having a centrally disp'osed .boss adapted 'tocontact with'saidsecondflnut"and a peripheral-portion adaptedxto contact'wijth theouter :sideof said spool-head, whereby said head may bejammed.tightlyaagainst the end of thespool barrel and ffirm'ly held inplace.
